FilterDesign Programs

The FilterDesign package is a pair of programs for designing linear phase Finite (length) Impulse Response (FIR) filters.

DFiltFIR

This program designs minimax approximation FIR filters. It uses the algorithm developed by McLellan and Parks. It incorporates constraints on the response as proposed by F. Grenez.

DFiltInt

This program designs minimum mean-square error FIR interpolating filters. The design specification is in terms of a tabulated power spectrum model for the input signal.
